Growth hormone (GH) is essential for liver regeneration after partial hepatectomy (PHx), with specific GH receptor (GHR) signaling pathways playing significant roles in the process.
Mice lacking GHR showed high mortality after PHx due to increased apoptosis and innate immune cell activity, while those with intact signaling mechanisms survived and regenerated their liver normally.
GH promotes the expression of the immunotolerance protein H2-Bl, which helps mitigate immune attacks during liver injury, indicating that HLA-G treatment could enhance recovery after liver surgeries.
